Question

The distance between Nihal house and her office is 25 km seat covers 5 km 5m by scooter 10 km 55 m by bus and rest on the foot how much distance she does she cover on foot

Answer 1

According the question, the distance between Nihal's house and her office                              = 25 km.                          ( given).

She covers by scooter  =  5 km 5m                    ( given)

By bus she covers        =  10 km 55 m                ( given)

Let us  consider the distance covered on foot = Pkm

∴Distant covers by ( scooter + bus + on foot ) = 25 km

⇒5 km+0.005km+10km+0.055km+P=25

⇒15.06km+P=25km

⇒P=9.94km

⇒9km 94m

Hence distance covered on foot will be 9 km 94 m.

Ans :- The distance covered on foot will be 9 km 94 m.

Answer 2

Concept:

• Calculating distances
• Converting units

Given:

• The total distance between Nihaal's house and office is 25km
• Distance covered by scooter = 5km 5m
• Distance covered by bus = 10km 55m

Find:

• The distance covered by foot

Solution:

The total distance between Nihaal's house and office = 25km= 25000m

Distance covered by scooter = 5km 5m = 5005m

Distance covered by bus = 10km 55m = 10055m

Distance covered by bus and scooter = 10055+5005= 15060m

Remaining distance = 25000-15060 = 9940m = 9km 940m

Nihal covers 9km 940m on foot.
